This idea
is for a fun trade item that's very inexpensive. Buy a package of plain pencils
and a package of erasers. Check around; you can usually get a package of 20
pencils and a package of 40 erasers for about $1
each. Leave the pencil unsharpened and put an eraser on both ends of the pencil.
Use a permanent marker and write the phrase on the pencil, as shown above,
"A WEEKEND WITHOUT GEOCACHING IS LIKE THIS PENCIL... NO POINT TO IT!"
